Abstract. Flexible free standing polymer electrolyte films have been successfully prepared using a blend of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly(vinyl chloride) (PVC) doped with lithium perchlorate (LiClO4). The conductivity of the film was influenced by salt concentration and the degree of crystallinity. An optimum room temperature conductivity obtained was 2.10...

A fire on the Mir space station in 1997 threatened the spacecraft and its crew of six [1]. The fire involved an oxygen jet leaking from a lithium–perchlorate oxygen generator. The fire involved three factors not normally encountered in terrestrial fires: enhanced oxygen, inverse flames (in that the oxidizer is surrounded by fuel), and microgravity. The present work examines some effects of thes...

The development of ion-selective microelectrodes for monitoring lithium ions in blood or serum is very important in the field of clinical chemistry. For this interest, all-solid-state microsensors based on impedance measurement for the detection of Li+ has been developed. The selective PVC membrane composition used was obtained by dissolving 1.2 % (w/w) Lithium ionophore III, 66 % (w/w) o-nitro...

Commercial aluminum foils were coated by graphene oxide, and its functionalized derivatives the corrosion performance of specimens examined in acidic conditions (lithium perchlorate sulfuric acid). Electrochemical experiments have shown that all oxide-coated provided up to 96% inhibition efficiency with a corresponding lower rate compared bare foil. Our results clearly show graphene-related mat...

Since the salting-in agents guanidinium chloride, urea, and lithium perchlorate increase the surface tension of water, the salting-in phenomenon does not reflect easier cavity formation in water. Therefore, these salting-in agents must be directly contributing to the solvation of a solute such as benzene in water, probably by a direct solvation interaction. The increased surface-tension effects...

A novel monomer of S-2-mercaptoethyl 2-(thiophen-3-yl)ethanethioate (MTE) were synthesized via esterification reaction between 2-(thiophen-3-yl)acetic and ethane-1,2-dithiol in the presence of dicyclohexyl-carbodiimide (DCC) and N,N’-dimethylpyridin-4-amine (4-DMAP) as catalytic system. The structure of monomer was characterized via MS, 1H-NMR and 13C-NMR spectroscopies. The electrochemical pol...

A dye-sensitized solar cell was constructed using a porphyrin photosensitizer and, in place of the usual iodide redox system, a solution in aniline solvent containing lithium perchlorate electrolyte, camphorsulfonic acid, and poly(ethylene oxide) copolymer. Irradiation generated polyaniline within the cell, initially following a proposed photoelectropolymerization mechanism, and eventually oper...
